ACIDIC SOLUTION FOR SILVER DEPOSITION AND METHOD FOR SILVER LAYER DEPOSITION ON METAL SURFACES

摘要

A processing solution and a method are used for producing solderable and bondablesilver layers the properties of which are not degraded even after storing, withno anti-tarnishing compounds being utilized as contrasted with prior art solutionsand methods. The acidic solution for silver deposition contains silver ionsand at least one Cu(I) complexing agent, said Cu(I) complexing agent being selectedfrom the group comprising compounds having the structural element (I).
